The Jag’s eighth consecutive league win saw them move five points clear at the top of the Highland League.
John McLeod added two more goals to his tally for the season, giving him 18 goals from 10 competitive games.
His second goal and Buckie’s fourth in the 54th minute was a 35-yard screamer which flashed past Kevin Main in the Turra goal.
Sam Urquhart had back-heeled Buckie into a 12th minute lead when Lewis Mackinnon guided a Jay Cheyne corner towards goal.
Turriff claimed Urquhart was in an offside position when he made contact with the ball right in front of Main.
It was 2-0 three minutes later when McLeod zipped a volley beyond Main from 10 yards.
The rampant Jags added a third after 23 minutes when McLeod turned provider for Chris Angus to sweep a shot under Main.
Angus hit the woodwork six minutes before half-time with an audacious volley from 35 yards.
Turriff had a great chance to get one back five minutes before the break when Ceiran McLean’s pass fell to David Booth.
The striker beat Greg Sim but Kevin Fraser showed great energy to get back to clear on the goalline.
McLeod’s stunner wrapped up the points early in the second half.
Booth and Andrzej Kleczkowski missed terrific chances to pull one back for the visitors from a miserable afternoon.
Buckie boss Graeme Stewart said: “That was their third game in seven days and I had watched them a couple of times, so I thought if we got an early lead their legs might go and that’s how it worked out.
“In the second half we controlled the game and didn’t exert ourselves too much.
“Every game is getting tougher and tougher now but we just keep going.”
Turriff Utd boss Ross Jack said: “We know the way they play, they try to get the ball forward as quickly as possible and we just couldn’t deal with it.
“Buckie have willing runners and boys who chase things and they do it well. We need to follow their example and start working a bit harder.”
